intermolecular direct biaryl coupling of benzoic acid derivatives and 1,3‐azoles has been developed. The key to success is the installation of an amide‐based bidentate coordinating group, which is easily removed and transformed into the parent ester groups after the coupling reaction. Kinetic studies indicate that the rate‐limiting step is the aromatic CH bond cleavage of benzoic acid derivatives.
热电偶:已开发出一种不含贵金属的铜介导的苯甲酸衍生物和1,3-唑类分子间直接联芳基偶合剂。成功的关键是安装基于酰胺的双齿配位基团,该基团在偶联反应后很容易被除去并转变为母体酯基团。动力学研究表明,限速步骤是苯甲酸衍生物的芳香族CH键裂解。
